10. Split String Elements by Spaces

Write a NumPy program to split the element of a given array with spaces.

Sample Solution:

Python Code:

# Importing necessary library
import numpy as np

# Creating a NumPy array containing a single string
x = np.array(['Python PHP Java C++'], dtype=np.str)

# Displaying the original array
print("Original Array:")
print(x)

# Splitting the single string in the array based on spaces
r = np.char.split(x)

# Displaying the result after splitting the string
print("\nSplit the element of the said array with spaces: ")
print(r)

Sample Input:

(['Python PHP Java C++'], dtype=np.str)

Sample Output:

Original Array:
['Python PHP Java C++']

Split the element of the said array with spaces: 
[list(['Python', 'PHP', 'Java', 'C++'])]

Explanation:

In the above exercise –

x = np.array(['Python PHP Java C++'], dtype=np.str): This code creates a 1-dimensional numpy array x of strings containing only one element "Python PHP Java C++".

r = np.char.split(x): Here the np.char.split() is called with x as an argument to split the string element of x into a list of substrings based on the default delimiter (space) and returns a 1-dimensional numpy array r containing a single element which is a list of the substrings.

For more Practice: Solve these Related Problems:

Create a function that splits each element of a 1D string array by spaces and returns a list of lists.
Implement a solution that uses np.char.split to split the strings and then flattens the result into a 2D array.
Test the splitting function on strings with multiple consecutive spaces to verify proper tokenization.
Combine the split output with a join operation to reconstruct the original string and verify accuracy.
